<p>Hi, <br>
During the intrinsic APIs implementation in stdarch, I find there are many llvm intrinsic APIs may contain types like llvm_v4i1_ty (4 bits), llvm_v2i1_ty (2 bits) for which I fail to find the corresponding types in Rust. We really need rustc to support it. We already started a discussion in <a href="https://github.com/rust-lang/rust/issues/81552">https://github.com/rust-lang/rust/issues/81552</a> , but few compiler experts give response to it. So I asked the question here for more experts' help.</p>
